Body development, carcass evaluations and lipidimia in male goats feed with linseed in the diet

Abstract

The study was carried out with objective to evaluate the effects of whole linseed addition in the diet of male goats on the development, blood and biochemical characteristics and on the Boer and Anglo-nubian males carcass. They were randomly divided in two groups balanced by breed, confined and submitted to diet with 9.5% of whole linseed and a control diet. The animals were observed from 4 to 12 months old and were evaluated on the body development, carcass yielding, feeding conversion, weight gain, biochemical levels of triglycerides, cholesterol and fractions, and on Longissimus dorsi muscle total fat, omega (ω) 3, ω-6, saturated fats, unsaturated fatty acids, ω-6/ω-3 ratio, saturated/unsaturated fats ratio were analyzed. The variables were analyzed by the BootStrap methodology. All the variables, with exception of triglycerides levels and Very-low-density lipoprotein (VLDL), did not present differences (P>0.05). So it was concluded that whole linseed addition in the male goat diet did not promote improvement in the body development, blood biochemical variables and characteristics of carcasses.
